Fault diagnosis of aircraft control surface based on ontology
HU Shou-song · Systems Engineering - Theory & Practice · 2012
The complexity of aircraft system was analyzed from the engineering point of view and the concept of aircraft family was introduced to the ontology modeling of aircraft.At the same time,the fault diagnosis of aircraft control surface was also studied.First,the domain knowledge model of aircraft ontology was built by Protege.Then the knowledge of single fault and combined faults diagnosis were listed as SWRL rules.Finally,the diagnosis result could be concluded through JESS reasoning to select the right plan of self-repairing.This method can be used to realize the modeling of complex systems and accurate selection of fault diagnosis plan.And the knowledge base of fault diagnosis can also be improved by adding new rules.
